Is there any way to remove the speckling in ecw files in no-data areas and re-output to ecw? There doesn’t seem to be a compression scheme for ecw that doesn’t produce these artifacts. I have tried the nearblack utility, but it doesn’t seem to be able to create or re-write to an ecw file.
Ray, To the best of my knowledge ecw compression is lossy, and not suitable to exactly represent nodata areas with a specific value. If you want to recover nodata areas you need to use nearblack, writing to a new uncompressed (or at least lossly compressed) output file in a format other than mrsid, or ecw.
